Fix Folder Tag Updating

[kzscisoft]

When using set_folder_details to update the tags of an existing folder the tags are not added on the server. This was discovered when addressing #105.

client = Client()
client.set_folder_details('/path/to/folder', tags=["test_tags"])

May or may not have something to do with the fact currently the server only accepts strings not lists.

For folder tags? That's not true - if I try to use a string, rather than a list, I get a 422:

{"detail":[{"loc":["body","tags"],"msg":"value is not a valid list","type":"type_error.list"}]}

so it definitely wants a list rather than a string.

The API works correctly as far as I can tell, e.g.:

curl -i -X PUT -H "Content-Type: application/json" \
        -H "Authorization: Bearer <token>" \
        --data '{"id": "KsUDKULkbc3ZX5oL4DaDGM", "tags": ["tag1", "tag2", "a1"]}' \

@alahiff my mistake, thanks for looking into this, must be on the client side
