BUG: Institution: 0 is removed from the Exceptional costs field and an information message is displayed after a new offering is created

[astridSABC]

Describe the Bug When an offering is created with "0" Exceptional costs, when you go back into the offering (edit), the "0" is removed from the exceptional cost field and an information message is displayed below the study costs.

Institution user would not know that their is an information message

Expected Behaviour "0" in Exceptional cost field was saved No information message is displayed

Actual Behaviour 0 is removed from the Exceptional costs field and an information message is displayed below the study costs.

Adding a "0" back in the Exceptional costs field immediately clears the warning message.

Note: Adding a "1" or other numbers greater (>) than "0" (up to 999,999) does not provide the information message.
