[JENKINS-23556] Git fetch fails when Repository URL is a Parameter with trailing whitespace

We have a job which passes the GIT_URL as a string parameter, supplied by the user. When the user does a Copy + Paste into the value field, sometimes a trailing whitespace is included. This appears to mess the plugin up somehow.

We are also using multiSCM, but I doubt it's related to the underlying issue.

If the Git URL is configured in the job config, the trailing whitespace is automatically trimmed when the job configuration is saved into config.xml. So this is only an issue if the GIT_URL is provided as a parameter to the job.

When the Git URL is a parameter, the whitespace is not trimmed, and the job fails during git fetch with the following log output:

Cloning repository git://my/git/URL.git

FATAL: Failed to fetch from git://my/git/URL.git

Not a big deal, as long as we know to trim the whitespace manually.
