Removing some not needed context

[pavelevap]

There are several "Mark as Spam" strings with different context. But we can merge string without context.

Also "In Response To" is needed for one context.

We can merge similar strings:

Invalid comment ID.
Oops, no comment with this ID.

See attached patch...

It would be also helpfull to merge following strings, I guess:

In reply to: <b><a href="%1$s">%2$s</a></b>
In reply to <a href="%1$s">%2$s</a>.

Something like "In reply to %s" would be fine for both cases. I can try to create patch if approved...

Comment string tweaks:

• Merge two strings about an invalid comment ID.
• Add missing context to 'Mark as Spam' string.
• Merge two 'In Response To' strings, replace redundant context with a translator comment.
