When KO, methods return labels with "," between each character

[GoogleCodeExporter]

Operating system and version (32/64bit) : Windows 7 64
Office name and version(32/64bit) : 2013
Browser name and version : FF 31.0
SeleniumWrapper version : 1.0.23.0

Before SeleniumWrapper 1.0.23.0, this problem was not present, and I think that 
it's a regression caused by the correction on issue 117.

Now, I have some "," characters between each character when a method returns 
"KO".

Example :
With 1.0.23.0 :
Method <verifySelectedLabel> failed! exp=<[V,A,L,L,O,U,R,E,C]> got<[]> 

Before 1.0.23.0 :
Method <verifySelectedLabel> failed! exp=<[VALLOUREC]> got<[]> 

I have the same problem with methods "verifyText" and "verifySelectOptions" 
(non exhaustive list).

KO, Method <verifyText> failed! exp=<[A,B,E,L,I,O,c]> got<[C,h,o,i,s,i,r, 
,A,B,E,L,I,O, ,A,C,R,E

Nevertheless, I prefer this 1.023.0 version because my issue 117 is OK...
