wasm: avoid LocalStorage past-the-end access on clear()
We were looping over all keys and removing the Qt keys
using an integer index. However, removing one key shifts
all other keys at higher indexes down one step such that
the loop eventually indexes past the end.
Fix this by getting the keys first in a separate step,
and then remove keys without relying on a stable iteration
order (which is also not guaranteed by the standard).
Pick-to: 6.4 6.5
