TASK: Remove un-necessary toString method in FusionPathProxy

[kitsunet]

This was needed at some point to evaluate the proxy to a string in a Fluid template,
but the way a proxy is handled was changed some time ago so that the respective
methods are called to get the content of the proxy instead of just string casting,
therefore it was no longer needed.

And the exception handling in the toString is not a good idea anyway (but necessary
because toString cannot raise exceptions) so all in all this method is undesirable and
as we don't use it anymore it should be removed.

This is basically the result of a long debugging session at the last sprint where we
implemented a short term bugfix and figured that we don't need this method anymore
and should remove it in one of the next releases.

Resolved the conflict, looks good to me codewise (looked for usage, but could not find any).
Could you give me a short info how come we don't need that method anymore, or why we had thiscode in the first place?

Please, can you give some info about why this is no longer needed?
