Partially revert 3071856a8e
Symlinking instead of copying the error-logger-extensions prevents the
app from finding the appropriate dependencies required in the error
logger extensions in the main process and in the renderer processes
because globalPaths are only set in renderer processes and /after/
error-logger-extensions are loaded.
We should fix this properly in a separate diff, and move the error
logger to isomorphic-core instead of copying it or symlinking it
