Using B2 with Crypt creates unnecessary requests

[tmazur]

When copying a directory to B2, with no changes in the directory - 4 requests are sent.

    b2_authorize_account
    b2_create_bucket
    b2_list_buckets
    b2_list_file_names

However when we setup an encrypted B2 we get 7 requests for the same scenario.

    b2_authorize_account
    b2_list_buckets
    b2_list_file_names
    b2_authorize_account
    b2_create_bucket
    b2_list_buckets
    b2_list_file_names

Version: rclone v1.33-72-ga4a44a4β
OS: Windows 10 x64
Storage system: B2

Quote from rclone forum:

rclone had to work out whether object i a file or a directory. It is doing this in an inefficient way at the moment by recreating the Fs. If you make an issue I'll look at fixing it.

This might need a new concept in the remote to fix properly - a Chroot call...

Could this issue be reopened?

I made a small improvement in this in 4ef30db which you'll find in the latest beta

The b2_list_buckets should be much quicker!
