`nvm_do_install` checked for its `nvm.sh` and `bash_completion` source lines with two separate regexes that each had to skip commented-out lines. Move that into `nvm_profile_has_line`, which strips whole-line comments before matching, and test the `bash_completion` line and an already set up profile too.
