EXT-7706 FIXED Implemented delayed friends cards synchronization and filling People/Friends tab with data until it is visible to user first time.

* Moved location of synchronization of the Friends/All inventory folder with friends list from startup to first requesting of data.
* Also updated "update Friends list" logic to be really trigged only when Friends tab is visible to user.

NOTE:
 * Friends List/All is filled with some delay on first opening.

TODO: refactoring is needed to switch code of updating People/nearby list to use the same approach as for Friends.
