Address review: extend None-return to UTR accessors

Transcript.five_prime_utr_sequence and Transcript.three_prime_utr_sequence
shared the ValueError crash with coding_sequence when the transcript
lacked a start_codon or stop_codon feature (same root cause — direct
calls to first_start_codon_spliced_offset / last_stop_codon_spliced_offset
fall through to _transcript_feature_position_ranges with required=True).
Return None from each accessor when the relevant codon feature is absent.

Extend the TAIR10 fixture with AT1G42615.1 (neither start_codon nor
stop_codon) and add assertions covering the 5'/3' UTR accessors on all
four fragment configurations, plus a UTR+CDS round-trip on the complete
transcript.
