Resolve "Remove SQL dumps of the app tests" #minor
- Closes #263
- deleted all the SQL dumps except test_consensus_N.sql
- all the tests (except some for the frontend mutation time plot) are loading pickle files instead of using MySQL
- some of the tests for the mutation time plot need MySQL since they need the information of the global_SNP table that is not exported to the pickle files
- it was coded that way because the global_SNP file would need too much memory allocation for larger datasets
- updated ray version to 1.13.*
