Add receive file rejection functionality

[JustusFT]

Currently, if the receiver tries to cancel the transfer on the ReceiveConsentScreen, the sender is not notified that the transfer was cancelled. This PR fixes that

Also needs LeastAuthority/wormhole-william#100 to be merged

Assuming fix of w-w part is correct, can we adjust behavior on frontend side, because now only Receiver side initiate rejections, also after rejection on Receiver side, it still stays in the same page (also Sender stays in the same page).

@donpui I updated this pr so that the sender and receiver resets back to the begin pages when a rejection happens. This pr as well as LeastAuthority/wormhole-william#100 should be ok now.

CI and for me fails to build:

#48 31.18     [tsl] ERROR in /usr/src/app/client/src/app/wormhole/client_worker.ts(243,19)
#48 31.18       TS2345: Argument of type '{ code: any; cancel: () => Promise<void>; done: Promise<void>; }' is not assignable to parameter of type 'TransferProgress | PromiseLike<TransferProgress>'.
#48 31.18   Property 'reject' is missing in type '{ code: any; cancel: () => Promise<void>; done: Promise<void>; }' but required in type 'TransferProgress'.

@donpui fixed the type error, it should be ok now

W-W merged and updated submodule. Additionally corrected E2E test to support current behaviour (@JustusFT take a look at last commit, before merging).
