[Bug]: OPF reader doesn't load title element if it contains file-as

[wtanksleyjr]

Describe the issue

Attached is an OPF generated by odmpy 0.6.2 (https://github.com/ping/odmpy/); it mostly works, but the title doesn't load. The problem seems to be the presence of an opf:file-as attribute inside the title element -- if I edit that out, it all loads perfectly.

metadata.opf.txt

Do you think this is fixable on ABS's side?

Steps to reproduce the issue

1. Configure ABS to prefer OPF metadata rather than folder metadata
2. Grab the provided file, drop it in a folder with an audio file so it looks like an audiobook, make sure the folder's name is something distinctive
3. Move into ABS's autoscan folder
4. Check to see that the audiobook's scanned name matches the folder's name, but everything else in the metadata comes from the OPF file
