fix(places): stop the place titles doubling the brand

Every place page shipped as 'Schools in Brentwood - Compare 27 Schools |
schoolcompare | schoolcompare'. The root layout's title template appends
'| schoolcompare' to any plain-string title, and all four place routes already
carried the brand. W8 opted the other routes out with an absolute title; the
place routes were written afterwards and did not inherit the lesson.

~2,600 titles affected, and the repetition pushed them past Google's
truncation point, so the doubled brand displaced real words in the result.

An e2e journey now asserts no title repeats the brand, across the static
routes and a place page, so this cannot come back on a route added later.
