remove quotation from tablename if exit

[RomikMakavana]

I've removed quotation mark if exist in tablename value. facing as issue during generation of file and also tablename

Database : PostgreSQL

I am using PostgreSQL, Ive created table in capital letters "SERP_feature"

When I have tried to generate migration file throw an error because filename must not include quotation mark

filename must be create_SERP_feature_table.php, where it takes create_"SERP_feature"_table.php

So, Pls accept my pull request and issue will resolve

Thank you,
