Provide additional logging

[Nitvex]

Background
At the moment, Ketcher has a lot of try/catch blocks which catch errors (for example, when parsing files) and show appearing errors in modal. This errors sometimes neither informative for end-user nor developers.

Solution

1. It is required to add console.error to catch block in order to easy find the places, where error appeared
2. It is required to prevent non-informative errors to be shown to users (Example error: "cannot read property null of undefined")
