Mysql 8 compliance (#19)

* Upgraded test db to mysql8, and flipped to mysql2 lib. Ran integration tests serially since test setup uses fixed ids. Prevented escape of select wildcard since that syntax is now invalid

* Upgraded typescript

* kill yarn file

* killed some debug and fixed if styling for pr
