This commit removes event listeners from the `script` element once loading is complete. If the element is not garbage collected properly, in Firefox, the script element still appears in the memory tree view, captured by `__zone_symbol__loadfalse -> HTMLScriptElement -> GC Roots`. We should always be good citizens and clean up event listeners when we no longer need them, as browser's garbage collectors work differently. Calling `remove()` on the node doesn't guarantee that the node can be collected.

I don't think I'm a code owner, but LGTM.
