Trim description before printing first line since there could be leading \n from multi-line template strings.

[indexzero]

Apologies for not including a test, but I wasn't quite sure where to put it: here, or in @oclif/plugin-help, or maybe in example-multi-js.

Lost quite a bit of time trying to figure this one out. The symptom is mycli --help displaying nothing for a given command.

The root cause around how template strings are interpreted.

If this description has a leading \n, e.g:

GoodbyeCommand.description = `
Describe the command here
...
Extra documentation goes here
`;

Then mycli --help will display nothing for that command. By trimming off any whitespace before parsing we ensure that this "gotcha" will be avoided by folks new to the framework.
