region query fails with `spans_prime_mer=True`

[danielsf]

The command

ztf_mar19.region(ra1=340.0, ra2=1.0, dec1=10.0, dec2=20.0, spans_prime_mer=True).count()

Results in

It runs fine if spans_prime_mer=False

After discussing with @ctslater, it seems likely that this block

235             return wrap(self._df.where(self._df.zone.between(zone1, zone2) &

    239         else:

needs parentheses around self._df.ra>=ra1 and self._df.ra<=ra2, so that pyspark can figure out the precedence of the comparisons.
