refactor(vue-app): simplify mount error log

[TheAlexLichter]

In case the mounting of the app fails, the error should be logged to the console in dev mode so it's easier to trace

@manniL For confirmation, dosen't it cause duplicate errors in console?

@pi0 Stacktrace in FF w/o

With the error logged

It's easier to trace then ☺️

[clarkdo]

I'm a little confused, because we already log error in default errorHandler, so is it only for less stacktrace? If so, I think we'd better optimize original log format.

The only difference is a error wrapper, may be we can change the wrapper to prepended message.

[pi0]

Maybe we can just pass the original error to errorHandler. [error while mountin] is not so useful for tracing.
