Added check that album art uri is a valid string

[darrynlowe]

Some Samsung TVs return a profile that has an "album_art_uri" property set to None. As-was, this caused a string handling error in the absolute_url call. Fix is to simply check that the uri is not null before the call.

Hi @darrynlowe, thank you for the PR! Can you add a test for this?

Thanks! Do you want a release with this?

[darrynlowe]

Thanks for merging in. No need for a special release for my sake given you release so frequently already (which is great, btw).

[StevenLooman]

There is a low chance of a change resulting from a home assistant issue. I'll await the results from that issue and create a new release after that.

[StevenLooman]

No activity regarding the home assistant issue. This weekend I'll create 0.38.1 to include this PR.

[StevenLooman]

I've released 0.38.1. I'm unsure if you were experiencing the issue via home assistant, but I'll create a PR there to bump this library.

[StevenLooman]

The release is already in home assistant, see https://www.home-assistant.io/blog/2024/01/03/release-20241/#release-202415---january-20

Hope this fixes the problem with your TV.

Works great - thanks for help!
