New and Edit Agreement panes: remove placeholder text

On the New Agreement pane and Edit Agreement pane, remove the placeholder text from the following fIelds:

• Agreement Status:
  • remove the default text "Select the status of this agreement"
• Internal contacts > Role:
  • remove text "Select a role for this user"
• Agreement-lines > Select-from-basket:
  • remove the text "Select e-resource or package
  • Change the field label text from "Select from basket" to "Select e-resource or package from the basket"
• License-information > Status (this agreement):
  • remove the text "Select a status"
• Organizations Name
  • remove "Select an organization"
• Organizations Role
  • remove "Select a role for this organization"

In each case, replace placeholder with " " (single space string). This replacement behaviour is based on these fields being mandatory, rather than optional.
