Bugfixes for 0.9.0

[stefan-niedermann]

• [x] Select more then one file in the listview and bulk delete them crashes the app (but deletes successfully) Not reproducable
• On first initial setup a network error is shown (since there is no server configured in this state, a sync error is odd)
• Server-URL-checkmark in settings activity is misaligned -> caused by using support library 24.2.0, bug is fixed in 24.2.1
• Test: Login has to fail if server side notes app is not installed (On first sync all existing notes are removed when server app is installed after client app has been used #131)

@korelstar your help is very welcome if you have some time :)

Do you mean "note" with "file" and this applies to the NotesListViewActivity? Then I can't reproduce this.

@korelstar not reproducable, maybe an odd state from my local machine.
I'm still receiving the sync-error at the very first opening:

Hmm. I can't reproduce the sync-error on first run with the current state in master. Can you debug this please? I will make a pull request with a more precise message and logging in a few minutes.
