Our eslintrc extends from 'wikimedia/client' which includes a
'no-restricted-properties' ruleset from the 'not-es5.js' file [1].
However, we were also including our own 'no-restricted-properties'
rules.
ESLint handle this duplication by clobbering instead of merging
so eslint-config-wikimedia's no-restricted-properties where not taking
effect and we were losing out on some guards against using es6.
This commit corrects that and makes both no-restricted-properties
rulesets merge instead of clobber as already done in MobileFrontend [2]
