We added support for multiple scan invocations on the same Reader in
this CL https://chromium-review.googlesource.com/c/chromium/src/+/2145263

Since Origin Trials feedback was to remove Filtering,
spec : https://github.com/w3c/web-nfc/pull/565
WIP CL : https://chromium-review.googlesource.com/c/chromium/src/+/2225770/
we tried to reason if in a world without filtering, multiple scans on
the same Reader is needed at all. The present thinking is to simply
reject scan promise when there's already an ongoing scan.
