LPS-44470 - Calendar resources search fall out of the screen

Hey @natecavanaugh,

Attached is an update for http://issues.liferay.com/browse/LPS-44470.

NOTE: "The reason behind this change, is that there isn't really a good way to ensure that an input append isn't going to overflow it's container.

We were already hiding the search button when the input append was inside of a navbar, we just took out that logic and made it more global, so that the same styling is being applied to an input-append that's inside a form-search, regardless of whether it's in a navbar or not.

I've seen this pattern a lot on various websites, so it seems like a safe solution." - @Robert-Frampton

Please let me know if you have any questions.  Thanks!
