Dig: do not hang on TLS context creation errors

There was a query_detach() call missing in dig, which could lead to
dig hanging on TLS context creation errors. This commit fixes.

The error was introduced because the Strict TLS implementation was
initially made over an older version of the code, where this extra
query_detach() call was not needed.
