HR fix 229827 - REST Java Client in web project cannot be deployed

REST Java Client in web project cannot be deployed
https://netbeans.org/bugzilla/show_bug.cgi?id=229827

Problem: the wizard adds Jersey jars to project classpath even when they 
are not required and that causes deployment of the project to fail

Fix: original author of the code prepared everything in place but in the 
end forgot to check "requiresJersey" variable. The variable is unsed. 
The fix just using the variable as was probably intended

Risk: low
