FIXED: login and ui errors in FreeRoom

Moved the user account check to the onResume method for FreeRoom. Fixed two issues: firstly, when logging in for the first time users experinced weird errors such as no date showing up, also,the time was not set to the current time. Secondly, upon deleting your account exiting the settings would still yeild the FreeRoom fragment rather then the login screen. Now the check is done at onResume so it will be checked at a more approprate time fixing the above mentioned problems.
