[TYPO3-mvc] RFC #7277: Non-required action argument thows Exception on unknown get-parameter uid

[Marc Bastian Heinrichs]

This is an SVN patch request.

Type: Bugfix

Bugtracker references:
http://forge.typo3.org/issues/7277

Problem:
Example arguments
?tx_blogexample_pi1[blog]=2&tx_blogexample_pi1[action]=index&tx_blogexample_pi1[controller]=Post&no_cache=1
When the index action of the Post controller is called with an unknown 
blog uid (here 2) an exception 
Tx_Extbase_MVC_Exception_InvalidArgumentValue is thrown also when
the action argument is set explicit to non-required by adding an "= NULL 
to the argument. So there is no chance to handle this inside the extension.

Solution:
Don't throw the exception when an argument is non-required.

Notes:
The patch has already an +1 by Felix in thread "Non-required action 
argument thows Exception on unknown get-parameter uid"
