Comment 1 for bug 1821945

This behavior is observed for other tests as well:

test_list_shares_by_share_network
fail
[x]

ft1.19: manilaclient.tests.functional.test_shares_listing.SharesListReadWriteTest.test_list_shares_by_share_networktesttools.testresult.real._StringException: Traceback (most recent call last):

This failure was also because there was a migration on the concerned share that completed between the "list" and the "get" calls here: https://opendev.org/openstack/python-manilaclient/src/commit/0ca91287acffece4f78451e160fafa040a988f5a/manilaclient/tests/functional/test_shares_listing.py#L154-L173
