Fix #21272 - Oracle inspectdb includes Views

Includes VIEWS in inspectdb output, bringing parity to Oracle. See https://code.djangoproject.com/ticket/21272
Yes, I do. Ending statements with semicolons is redundant at best (as used here); if followed by whitespace, the semicolons can actually break things. Code in tests serves as example, and so shouldn't include them.
This is essentially like pep8 issues -- you don't have to clean up old code, but please avoid introducing new ones.
