Mina doesn't fully resolve the host key

[vs49688]

The ecdsa-sha2-nistp521 key is missing the trailing aA== causing a key verification error.

Command:

./nimw.sh resource add flashlite pbspro -- --uri=ssh://username@flashlite.rcc.uq.edu.au --key /path/to/key --limit=10 --max-batch-size=2 --add-batch-res-scale=ncpus:1 --add-batch-res-static=walltime:01:00:00 --add-batch-res-scale=mem:1GiB -- -A UQ-RCC
