fix(toolkit-install): fix set -e exit in preflight() when LE_EMAIL empty (v1.0.2)

preflight() last command was '[ -n "$LE_EMAIL" ] && log ...' which exits 1
when LE_EMAIL is unset. With set -euo pipefail, the function returned 1 and
the caller's set -e immediately exited the script. Convert to if...fi form
so the function always returns 0.
