Files Databases Are Always Downloaded When Installing Updates

Created by: lots0logs

This was originally reported on #272 (closed) and it still occurs in the latest version of pamac.

From #272 (closed):

Currently Pamac automatically refreshes the databases when you click install updates. Often times refreshing is unnecessary because it was just refreshed prior to showing the available updates. However, I know that depending on the user's settings there will be times when the refresh is necessary. I think it would better if the *.files databases for each repo were not downloaded when performing a refresh prior to installing updates. The *.files databases are much larger than the normal databases and so it delays the whole process quite a bit.

PR coming shortly...
