[Development] Please avoid shell-special row names in QtTest

[Thiago Macieira]

Re: https://bugreports.qt.io/browse/QTQAINFRA-5085

Please don't use spaces, wildcards or other shell metacharacters in your test 
row names. Because of the different shells that we must go through, and in some 
cases the number of shells (try to use ssh to run a test remotely), it gets 
annoying very quickly and leads to bugs.

So as a kind request, please use simple words and phrases as your test rows. 
Dots, dashes, slashes, commas, plus signs, equal signs, colons are fine. 
Spaces, asterisks, parentheses, brackets, backslashes are not. I think the at-
sign has problems on powershell.
