Update index name quoting in MySQL table creation

When creating a table that includes an index named with a reserved keyword the index name isn't quoted. When creating the index specifically the name is quote. This bring the table generation SQL inline with the index generation.
Ah, my first iteration of code quoted the index name within the MySQL platform file. Now that it is in the 'AbstractPlatform' class you are quite right that the test should be updated to reflect this.

Bit slow there, will take a look when I get some time.
