Identifiers are not escaped after merging

[nigredo-tori]

Config:

OrganizeImports {
  groupedImports = Merge
}

Input:

import org.http4s.headers.`Cache-Control`
import org.http4s.headers.Location

Output (note the lack of backticks):

import org.http4s.headers.{Cache-Control, Location}

Tested with OrganizeImports 0.4.0 and 0.5.0.

@nigredo-tori, Scalafix 0.9.26 had a regression and may cause this issue. See scalacenter/scalafix#1337 and scalameta/scalameta#2260. Any chance that you are using Scalafix 0.9.26+?

I added the following test changes to master but could not reproduce this issue:

I was using Scalafix 0.9.19 in my project.

The thing is, when running scalafix via SBT I actually don't get this error. This only happens when I run the corresponding task in Metals. So it seems like Metals uses a buggy scalafix version (0.9.27 FWICT).

Thank you. Sorry for not minimizing the issue before posting.
