Ampersand not encoded when used in search string

Overview:
Affects Nolana and MG, but not current master
Affects all search boxes in agreements and licenses search & filter panes
Searching for a term like `A&AePortal` does not produce expected results

Steps to Reproduce:

1. Log into https://bugfest-nolana.int.aws.folio.org/ or https://bugfest-mg.int.aws.folio.org/
2. Carry out a search for `A&AePortal`
3. In developers console note the Request URL has parameters:
   `erm/sas?
   match=name&
   match=alternateNames.name&
   match=description&
   term=A&AePortal&
   filters=agreementStatus.value==active%7C%7CagreementStatus.value==draft%7C%7CagreementStatus.value==in_negotiation%7C%7CagreementStatus.value==requested&sort=name;asc&stats=true&perPage=100&offset=0`

Expected Results:
Expect that the ampersand in `A&AePortal` encoded as %26 to avoid this being treated as a join between parameters

Actual Results:
ampersand not encoded so interpreted as a search for `A`
Additional Information:
Seems to be fixed in current master branch as I cannot recreate in snapshot environment
