Martin Hořeňovský b819432271 Don't clear out all messages upon printing an assertion.
Previously, this would not print out any messages for the last CHECK
```cpp
TEST_CASE("Foo") {
INFO("Test case start");
for (int i = 0; i < 2; ++i) {
INFO("The number is " << i);
CHECK(i == 0);
}
CHECK(false);
}
```

now it does.
