Fix prefixing bugs for d.bs parameter default values

[TwitchBronBron]

Fix bugs in the prefixer related to d.bs default parameters. For example, lib.d.bs:

function doSomething(cb1 = alpha.beta)
end function

Should now properly get prefixed to:

namespace logger
    function doSomething(cb1 = logger.alpha.beta)
    end function
end namespace

Also works for default values such as:

• p1 = alpha.beta()
• p2 = someFunc(alpha.beta())
• p3 = alpha_beta
• p4 = alpha_beta()
