shell completions for fish shell don't complete for paths on `trash` command without `put`

[m4rch3n1ng]

pressing <tab> on the trash command only auto-completes for the commands, not the files in the directory. trash put completion works as expected.

i don't know how "clap_complete" works, but you can fix the completion by prepending the line complete -c trash -F to the automatically generated completions.

i only know about fish, but zsh still seems to be broken as of #57.

dropping trash in favor of trash put like suggested in #57 (comment) would obviously work as well, but would be a major breaking change and the loss of a selling point.

I'm in favor of dropping trash <file> if it helps provide reliable completion, I wrote why here: #57 (comment).
