tests: fix compilation warning in tests/tst-run.cc It is generally a bad idea to catch exceptions by value, because it forces an unnecessary copy of the caught value. It's even worse when the type is polymorphic - in that case the copy will only be a slice of the original type. This is why recent compilers started to warn when code catches a polymorphic type by value. In the specific case fixed here, the warning is spurious, because the caught exception isn't even used. But it's trivial to fix it, and get rid of one more warning during test compilation.
