Missing space in IRC notifications

When a build fails, jenkins messages me privately on IRC to say

Build app isSTILL FAILING: https://...

("app" is the project name, "STILL FAILING" is bold red).

Note the missing space between "is" and the build status.

Public notifications to the channel are also missing a space in front of the build status:

Project app build #2129:STILL FAILING in 19 min: https://...
