[UI] Cannot remove tags on host and primary storage

[slavkap]

If there is only one tag for host/primary storage it's not possible to remove it. The workaround is to replace the tag with a comma ",". In the old UI, this functionality works correctly

API call from old UI is:

/client/api?command=updateStoragePool&id=c9b09777-7340-3752-8a96-f3835f9f5c53&tags=&capacitybytes=273804165120&name=test2&response=json&_=1611312734947

API call from new UI the tag value with an empty string was not get:

/client/api/?id=c9b09777-7340-3752-8a96-f3835f9f5c53&name=test2&command=updateStoragePool&response=json
