      Bug#13113222 RQG_SIGNAL_RESIGNAL FAILED WITH ASSERTION.
      
      The triggered assert checks that a matching condition is
      found inside the diagnostics area when a handler is activated.
      It was triggered in this case if the diagnostics area was
      full when the condition was reported (e.g. the area already
      contains max_error_count conditions). This meant that the
      diagnostics area did not contain a matching condition when
      the handler code tried to look for it.
      
      This was a regression introduced by WL#5986.
      
      This patch fixes the problem by temporarily making a condition
      in such cases so it can be handled properly.
      
      Test case added to sp-error.test.
