Fix mutation of date param in MomentUtils.formatByString

[crudh]

MomentUtils.formatByString takes the date param and changes it by setting a locale.

Everywhere else in the file clone is used but not here. So it's an unexpected mutation of a passed param and it blows up if date is frozen.

The only changes are in the formatByString, the rest was applied by husky on commit.

This is the actual change.

Sorry for long response, I was on vacation.

Thanks for the change, but it looks like your local prettier configuration conflicts with our.
Could you please run prettier on all files yarn prettier --write './src/**/*.{js,jsx,ts,tsx,json,css,md,mdx}'

@dmtrKovalenko fixed now!

Seems like the husky/lint-staged rules runs prettier with the global configuration instead of the local one? It did the reformatting earlier. I disabled it temporarily and then everything was fine.
