fix(createMigrationsTable): Fix bug where already-quoted search path components could get double-quoted when creating the mirations table.

Postgres's `SHOW search_path` returns the search path as a comma-separated string with spaces, like `"$user", public, "another-quoted-schema"`, so checking whether the _first character_ of a search path component is `"` is not sufficient. Instead, just check whether the search path component contains quotes at all, and don't add any quotes if it does.
