Don't crash app when TagManager crashes

Swallow TagManager crashes as per https://productforums.google.com/forum/#!topic/tag-manager/87Kb_TZv79w
Update version number, use exact version numbers for dependencies
Use default options for getRelativeTimeSpanString

Hopefully work around issue with format conversion exception for Brazil locale
Don't use cursors that have already been closed

Null out Cursor on closing it and then check against a null Cursor to prevent crashes.
