Add cases to switch in ModelTypeToString

Some sync integration tests will attempt to get the string for the model type
TOP_LEVEL_FOLDER when the tests are running in very verbose mode (--v=2).
Because there was no case for this type in the switch statement, the tests would
run into a NOTREACHED() assertion.

This change adds the case statement necessary to avoid the NOTREACHED in these
tests.
