This makes sure long strings as `actual` or `expected` values on an
`AssertionError` won't be logged completely. This is important as
the actual value is somewhat redundant in combination with the error
message which already logs the difference between the input values.
In some edge cases an identical line could be printed twice. This is
now fixed by changing the algorithm a bit. It will now verify how
many lines were identical before the current one.
So far consequitive identical lines were collapsed if there were at
least three. Now they are only collapsed from five identical lines on.

This also simplifies the implementation a tiny bit by abstracting some
logic.
