#93-94-101-109 Deletion of resources and tags fixed

[CloudLevi]

• fixed #93 and #101 crashes
• fixed incorrect resource opening (#94)
• fixed crash when deleting a resource in GallryFragment and going back to ResourcesFragment (temporary solution to avoid crash itself, further fixes and testing needed)

Moving #101 into scope of #117

93 and #94 do not reproduce in main, after we have #122 merged

@CloudLevi could you look if it makes sense to catch-up main?

Didn't notice this line:

fixed crash when deleting a resource in GallryFragment and going back to ResourcesFragment (temporary solution to avoid crash itself, further fixes and testing needed)

This is #109 and it is pretty important. Maybe it would be easier to extract the solution into new branch.

Actually, if it's only the workaround consisting of mocking AssertionError then it can be safely closed.
