URLs missing via import from kdbx database

[perry-mitchell]

Hi. URLs do not import from kdbx databases in v1.6.1 on MacOS

From buttercup/buttercup-desktop#593

After testing the iOS mobile app I see that a URL field is not included when adding database entries, but can be added as a meta field with no hyperlink support. I’m sure databases vary between password manager imports, but it would be useful to auto-populate such fields, or at least drop them in a catch all field for the time being, rather the data entirely.
