Web Inspector: `inspector/debugger/breakpoints/resolved-dump-all-paus…

…e-locations.html` is a flakey failure

Reviewed by Devin Rousso.

This test was flaky because the only piece of code in the test keeping the SourceProvider alive for `dump-multiline.js`
was the `function test()`, which is replaced by the `function test()` in the test page itself. This meant that the
function from dump-multiline.js would be garbage collected at some point, and since it was the last possible way to
reach source code in `dump-multiline.js`, the SourceProvider was also disposed of at the same time.

Normally this would not be an issue for users because the source code itself is still viewable in Web Inspector, and
breakpoints can still be set (and will be triggered after a reload). The issue here is that when we attach Web Inspector
the source code is longer reachable, so the backend doesn't send information for it to the frontend for it (until a page
reload), but this test is assuming the script will have been sent from the backend to associate with the resource.
