Fix schema dumping when the view has spaces in it

[barendt]

When the name of a view has spaces in it, the oracle_identifier method in Scenic::Adapters::OracleEnhanced::Views will quote the view's name such that the indexes method of the Oracle Enhanced Adapter won't work properly.

Solving this will require looking at all of the places where the name of the new Scenic::View object is used to determine if, and how, it should be quoted.
