Fix manage tempest test validation

Tempest test test_manage_with_type_invalid always passes
because if scheduler mistakenly accept the share type and
host combination, manage operation will fail in the backend
and test would assume it failed for the correct reason.

Part of the fix is ensuring share being managed exists, so
status becomes 'available' if scheduler accepts the share.
Since this test, which is originally a negative test, requires
the resource in the backend to exist and be cleaned up, share needs
to properly be managed again to be deleted. This is exactly what
another separate test does. Originally both test cases were merged
in a single tempest test, possibly for this purpose, so this change
addresses the bug by merging them back.
