Fix port-forward name clash

If you have two pods, with similar hostnames, such as:
- somepod
- somepod2
Then the grep would previously capture both, and try to assign IPs
like `192.168.252.10\n11`, which is obviously not quite valid.
This should make it such that the grep will only match when the
name is complete
