Importing to directory-based journals doesn't do anything, and has incorrect message

[wren]

Bug Report

Environment

• Jrnl version: v2.4.3
• Install method: pipx
• OS macos 10.15.3

Current Behavior

$ j -2 --export text | j dirtest --import
[2 imported to default journal]

The above should be importing to the dirtest journal, but it says it's importing to default (it's actually not importing anywhere).

Expected Behavior

Users should be able to import journal entries to directory-based journals the same way they can to single-file journals.

Repro Steps

1. Make a directory-based journal (create an empty directory, and add to config as dirtest or whatever)
2. Add an entry to it (e.g. jrnl dirtext some new entry) to make sure it works
3. Try to import any number of entries to it from another journal (jrnl --export text | jrnl dirtest --import, or jrnl --import -i journal_file.txt)
4. Observe the message saying entries were imported to default journal
5. Observe entries were not actually imported to either journal (jrnl -1 and jrnl dirtest -1 or however you want to try to find those entries)

jrnl version v2.4.5
I was looking into trying the directory-based jrnls, but this appears to be the case for me too.
