OTC-254: Android 10/11 Compatibility in Claims app - part 2

[sniedzielski]

TICKET: https://openimis.atlassian.net/browse/OTC-254

Please get to know with the changes. I created them during fixing bug on init start app on Android <=10. Error was due to too quick processing file/folders before granting perms onCreate in MainActivity.

changes:

• processing files/folders path etc in "onRequestPermission" when the perms are granted
• moving 'refreshCount' to the "onRequestPermission" when the perms are granted
• check if db file exists - if exists - then only ask for admin code without init db again. If db doesn't exist then init db/create tables and fill data.
• remove processing claims from "trash" folder when we click "Upload claims" in "Synchronize" (discussed with @delcroip on Thursday)
• move to the "Trash" folder also JSON files when we click "Create XML" in "Synchronize" (discussed with @delcroip on Thursday)
• count "pending" folders only from pending claims, not pending+trash

also includes one of the change dedicated for this ticket https://openimis.atlassian.net/browse/OTC-255

• this change is about processing db path into proper folder.

I tested my changes on MV:

• emulators with android 10/11
• real devices:
  a) Lenovo with Android 7
  b) Samsung Galaxy with Android 11
