[UI] "Leave site" warning on stock adjustment/Receive/Issue page pops up unnecessarily

@Nick Reid @Brandon Bowersox-Johnson @Mary Jo Kochendorfer
This bug has already fixed, you can review it on the test server.
For now, the model should only show up IF changes are actually made.

It's fine with me too (specifically, it's fine that the Team ILL folks at VillageReach will deal with text changes later).

@Shiyu Jin – I just removed AC #2 and #3

We can deal with text changes later when/if needed....

@Nick Reid
Thanks for your feedback.
Regarding your suggested AC, we are happy to do the first one. The modal only appears when there is a change.
However, we are not sure about your #2 and #3 AC. Your suggested text is our original text but later based on the feedback we change it to the current text.
