Null Pointer exception if junitOutputDirectory do not exist

[Google Code Exporter]

What steps will reproduce the problem?
1. specify a custom junitOutputDirectory which do not exist in file system 
2. start the unit tests
3. Null pointer exception

What is the expected output? What do you see instead?
I expect the soft to create the output directory if it do not exist.
Instead the soft has crash while trying to delete older files.

What version of the product are you using? On what operating system?
the-missing-android-xml-junit-test-runner V1.1

I included a patch file which check if the directory exist (and create it if 
not) before calling deleteOldFiles method. I also added a null check in the 
method.

Please provide any additional information below.
