A recent sourcemap bug fix (getsentry/rust-sourcemap#129) results in some minified lines/columns being (correctly) unmapped. We cannot incorporate this bug fix into Symbolicator without first adjusting these tests because they are also run in the Symbolicator repo. This PR temporarily removes assertions about the unmapped frames so we can merge the fix (it's contained in getsentry/symbolicator#1749). After Symbolicator is merged we can properly assert that the frames in question are unmapped. As a side note, this entire test is somewhat bizarre. It was added in c5d2742 in more or less its current form. The first frame the test attempts to map has line 9 and column 2321, but no line in the source file fixture has that many columns (the test works regardless, but still, I can't fathom what the idea behind this is). Moreover, the fixture apparently got reformatted by mistake in the unrelated 6c11c9b, which makes no difference to the correctness of the test but makes it very confusing if you look at it in a sourcemap visualizer. Therefore we also restore the original fixture here.

This correctly interprets sourcemap tokens that only have a minified column number as "unmapped". Previously, such tokens would inherit the source line and column numbers from the last valid token, but that is incorrect. Now we set the numbers to
u32::MAXfor such cases.Fixes #105. Fixes RUSTSM-10.
