the timestamps of the line and plays are now saved
when the player sets a value for a category, and then deletes it, the changes are saved to the local storage
Merge pull request #4 from sebastianamaro/fix-emptyTimestamps-deleteInsertedCategory-client

Fix empty timestamps and delete inserted category when needed --> Client
first approach to the strange error
When player creates game, he is searched by registrationId in the db. If not found, new one is created. If found, it has the gameId added to its list. In both cases the game adds the player to its array.
Still trying to fix it..
finally fixed! :D
