Removed unnecessary queries from YarhtziehtAccess

The only queries necessary are
* A specific instance (with all the data)
* By date (currently a specific date, later a range)
* All Yarhtziehts connected to a given person
* A single row based on the Id in the database
Removed tests for conversion methods

The conversion methods are basic to point of just translating from one
field to another, and therefore it is not worth the effort to write UT
that could be replaced with an eye check
Updated MySql and worked on testing

Minor changes to the database - removed AutoIncrement
