Prevent loading ontologies with test environment
Do not check DB name when checking test env

The database name should not factor into the decision of whether or not
the environment is a test environment. E.g., I have many test databases setup,
and they are named qiita_test2, my_qiita_test, etc.
Remove unused ENVIRONMENTS global
Remove ENA_test ontology

Taking a different approach instead: do not allow ontologies to be laoded
if it is a test environment
Typo: forgot to close string
Fix minor typo; thanks @ElDeveloper!
