Bug fix for host parameter issue with lists

[damianj]

As explained in #1772 there is an issue when using a list as an argument for the host parameter in the Blueprint.route() decorator. I've traced the issue back to this line, and the if conditional should ensure that the name attribute isn't accessed when route is None.

This seems like an okay change. But, it might be nice to have a test with host routing with a string and a list of strings.

Thanks for the PR.

[damianj]

@ahopkins I think the tests are being addressed in #1775? Unless that is not addressing Blueprint.route() tests.

[damianj]

@ahopkins I added some unit tests for using lists with the host parameter. There were already some for testing strings with the host parameter.

@ahopkins can you resolve your change request if you think that we've met your threshhold?

[damianj]

Just following up to see if there is anything else I can or need to do in order to get this merged?

#1775 was closed (stale) and this now has tests. Can we resolve this change request and get this merged?
