Skip FirefoxAccounts during Firefox CSV Import (#323)

* Skip FirefoxAccounts during Firefox CSV Import

Firefox exports 'chrome://FirefoxAccounts' if Firefox Accouts are used
in browser. It's quite hacky - password field in CSV is actually a JSON
encoded data, not a password.
Because it's not a useful record, it should be skipped during import.

* Fix indentation

* Move test Firefox test data to files, fix linter errors
