Regexp takes only last character of first group

[krisavi]

According to regex it seems to take only last character of the first group instead of full part.

Reactify-Django/src/reactify-ui/package.json

Line 25 in 14339fa

"build-rename-logo": "renamer --regex --find '([^\\.])\\.[^\\.]+\\.(\\w+)' --replace '$1.$2' build/static/media/*",

to fix it the first group should be like: ([^\\.]+)

Update: tested it with incorrect format and it seemed to even work correctly, even though according to regex it should only take last character, i.e. logo.f0e512c7.svg to o.svg
