Spike: User With No Expiration Treated as Expired in Proxy Relationship

Description from BugFest test: Trying to add a proxy for user Adkins, Gregory returns message "Sponsor user record expired". This message is not displayed when Adkins' user record is updated in any other way.

Steps to repro:

1. Log into folio-snapshot
2. Go to users and pick a user and populate the user expiration date to somewhere in the future (I am talking about the user expiration date up in the User Information section)
   
3. Go to edit a second user record
4. Clear out their expiration date, if populated and save
5. Edit the second user record again
6. Scroll down to the proxy section and add the first user as a proxy

Actual:

• The relationship status box says "Active" but is red with text reading "Sponsor user record expired"
• It seem that the system is interpreting the empty user expiration status of the second user (the sponsor in this case) as expired

Expected: The proxy relationship is supposed to become inactive if any of these things happen:

1. The proxy relationship expiration date has passed
   
2. The proxy user record has expired
   
3. The sponsor user record has expired (same field as #2 above but for the sponsor's user record)

What appears to be happening here is:

• BUG 1: The system is treating an empty user expiration date as expired in this case. CB: This seems to be fixed
• BUG 2: when a proxy relationship is inactive because of one of the above reasons, the menu should say "Inactive", not "Active"
• BUG 3: having an inactive proxy/sponsor relationship shouldn't prevent you from being able to save the record
• BUG 4: after having added a proxy/sponsor relationship, I attempted to change the user expiration date (not the relationship one) to a date in the past and the form simply wouldn't save despite being dirty. What should happen is the form should save and the proxy relationship should become inactive.
• BUG 5: after expiring the sponsor user record, the message under the message under the Proxy relationship status says "Proxy user record expired". It should say "Sponsor user record expired".
  
• BUG 6: after expiring the sponsor user record, the message under the message under the Proxy relationship status says "Proxy user record expired". It should say "Sponsor user record expired". NOTE: The wrong message is also displaying on the popup at Check out and in Requests. Do I need to file separate bugs for these issues?
