fix(remote): make sure api calls reject before browser is closed (#31858)

Browse Source 
Upon calling `browser.close()` or dropping remote connection, make sure
to reject api calls before resolving `browser.close()` and firing a
`disconnected` event.

This change aligns the order guarantee with non-remote case.
