[PR #7061/e75dc746 backport][stable-6] bitwarden lookup fix get_field

[patchback]

This is a backport of PR #7061 as merged into main (e75dc74).

SUMMARY

A bitwarden record without any custom fields will throw a KeyError when you try to search with field='notes'. The code here tries to open match['fields'] without first checking if the key fields exists in match.
It turns out that with the current logic you can't get the notes field. It's either the login fields or custom fields. The new logic looks for your key in custom fields, then in login fields, then in the general fields for that record.

Fixes #6617
