omemo: Check for 1 alongside true in an omemo encrypted message stanza

Browse Source 
prekey is defined as `<xs:attribute name="prekey" type="xs:boolean"/>`
which allows both `true` and `1` as truthy values.
Not checking for `1` breaks omemo encryption when interacting with
clients which set prekey="1", example: psi+ 1.4.983
