It seems that if an axis value contains a space, the next time the configuration
is read it is parsed as two values.

Steps to reproduce
1. Create a matrix job
2. Create an axis
3. Enter "Debug Code1", "Debug Code2" as values in the axis. Note that you must
have " around each value otherwise it will not work.
4. Save
5 Verify that there are only 2 axes displayed in the page
6. Re-open the configuration page
7. Save

Expected outcome:
There should only be two axes displayed in the status page

Actual outcome:
There are 4 axes displayed
