Remove local contact access code where needed

[SBiOSoftWhare]

Now we just need to access local contacts in StartChatViewController. If it will be removed in global search.
Look at occurrences of BuildSettings.allowLocalContactsAccess. And remove code that it's not needed anymore.
Fetch local contacts at the last moment and remove (or move) the global fetch from LegacyAppDelegate.refreshLocalContacts
