[LyX/master] Add missing 'break' for four default cases in VCBackend.cpp

[Christian Ridderström]

commit 95e7abadc0e3c8c250c25b0c5f27575644b94ca7
Author: Christian Ridderström <c...@lyx.org>

    Add missing 'break' for four default cases in VCBackend.cpp
    
    Replace four cases of 'default: ;' in VCBackend.cpp with
        default:
            break;
    
    Justification: Make consistent with the rest of the LyX source code.
    I found no other occurences of 'default: ;' in the source.
