Improve confusing phrasing (#402)

I find this phrasing ("Under no circumstances User approval [...]") confusing.
It initially seems like a misprint with one sentence suddenly interrupted by the
other, which then becomes "User approval to present data from their Wallet Unit
should be construed as lawful grounds [...]" which appears to be the opposite of
the intended meaning.
