"Pinning a file is not supported" without -p option

[timbremer]

Hi, awesome tool! I only have one problem: I'm trying to send a file (don't know if I'm doing it right, I'm specifying the path as file name) but is shows me this error:
{ error: { err: 'pinning a file is not supported', message: undefined } }
which is really strange because I am not using the -p option for pinning the message.

#16 didn't fix this error:
$ slackcli -h ****** -f app/build/outputs/apk/app-beta-debug.apk -m "New test apk:" -u ****** -i https://bytebucket.org/************/web_hi_res_512.png?token=************ error: { error: { err: 'pinning a file is not supported', message: undefined } }

This issue should be reopened.
On slack-cli@1.0.18

$ export SLACK_TOKEN=#####
$ slackcli --file ### --channel ###
error:
{ error: { err: 'pinning a file is not supported', message: undefined } }
