no-relative-parent-imports didn't check if path start with './'

[Alex-Sokolov]

When add rule to config
import blockIcons from '../../components/test/test.js' — FAIL
but
import blockIcons from './../../components/test/test.js' — OK

ref: #1093

we may want to use the resolver here to normalize the paths?
