Remove 'Top padding' string from ConfigurationWizard (Bug #5260)
A bit more clean and concise.

I've added "from providerlistfragment" just in case there is any other "top padding" string suitable in other class in the future.

I've removed the auxiliar variable in the block of code from ProviderListFragment, there is no need of if now we have a constant in that class.
