Incorrect error with cbbackupmgr collect-log and --output-dir

Problem
When a file path is provided instead of a folder to -output-dir argument of the collect-logs subcommand the error prints the repo incorrectly instead of the value passed to -output-dir

Steps to Reproduce

1. Create a repo

cbbackupmgr config -a arch -r repo

2.

/opt/couchbase/bin/cbbackupmgr collect-logs -a arch   -o /never

Collecting logs from arch failed: no such file or directory

Expectation
For the correct error message to be produce

/opt/couchbase/bin/cbbackupmgr collect-logs -a arch   -o /never

Collecting logs from /never failed: no such file or directory

Work around
Provide the correct value to --output-dir
