The index catalog should fail the initialization process for a collection with >1 text index. This would eliminate logic in the query planner and query stage builder that handles the >1 text index case, since it would be impossible to open a collection (and as such, impossible to issue queries) with >1 text index.

Notes:

• It is possible to create >1 text index on a collection in 2.4, and it is not possible in 2.6.
• In both 2.4 and 2.6, having >1 text index prevents use of the text command and $text query operator.
