test: relax @test_throws ErrorException to also allow BoundsError (#1431)

An issue with `Base` is that some methods of `size` throw `BoundsError`
for an out-of-bounds second argument, while others throw
`ErrorException` in the same case.

Relax the tests here to allow for fixing that issue in `Base` in the
future.
