Block on index available in testsmango_test_fixes

When creating a Mango index in the Elixir tests, we need to
block until the database reports the index as available. This
workaround was present in the python Mango tests but did not
get ported to Elixir when the partitioned Mango tests were added.

Presumambly this is needed to workaround an underlying race condition
between the index write and the ddoc cache.
