[diaspora] Cleanups and type-hinting (#665)

* [diaspora] Fixes/cleanups:
- added curly braces/spaces for better readability
- don't use count() when you can use DBM::is_result()
- used proper type-hints `App` and `array`
- "imported" Friendica\App

* [diaspora]: Fixed parser error, ops

* [diaspora]:
- DBA::isResult() is now the new name (MrPetovan)
- added spaces for nice indending and better readability
- changed 4-spaces to tab
