Overwriting of PHPUnit TestCase properties

[cHeeSaW]

Describe the bug
When the tested class has parameters in the constructor which are named like properties of the PHPUnit TestCase class, these would be overwritten after using quickmock

To Reproduce
Steps to reproduce the behavior:

1. Create a class with a contructor parameter called data
2. Create a test for this class
3. Use quickmock
4. See error

Expected behavior
Maybe detection if TestCase already reservers a name and rename the generated property

Whenever mock names collide with existing inherited properties, a suffix will now be added to the name to distinguish them.
