Fix selecting a profile ticking every M365-only and GWS-only user

_applyPendingProfileUsers() set u.selected = matches(u), where matches()
was `wanted.has(u.id) || (u.googleEmail && ...)`. For users without a
googleEmail (every M365-only and Google-only user) that evaluates to
undefined, not false — and both renderAccountList() and getSelectedUsers()
treat anything other than false as selected. So applying a profile ticked,
and would have scanned, all of those users in addition to the profile's own.

Coerce the googleEmail branch to a boolean.

Reproduced against a copy of real data: a 1-account profile ticked 56
(37 M365-only + 18 GWS-only extras); after the fix it ticks 1, and every
profile ticks only its own stored accounts.

Regression from bbe9c62 (released in 1.7.10).
