Bug Report

Current Behavior
Adding the u flag to a regexp with a named capturing group causes babel to crash if any transform related to unicode regexps is also enabled. This happens even when the named capturing group transform is enabled in preset-env, likely due to plugin execution order.

Input Code

• REPL link

void /(?<test>foo)/u

Expected behavior/code

void _wrapRegExp(/(foo)/, {
  test: 1
})

Babel Configuration (.babelrc, package.json, cli command)

{
  "presets": [
    "env"
  ]
}

Environment

• Babel version(s): 7.4.3
• Node/npm version: 12.6.0
• OS: macOS 10.14
• Monorepo: yes
• How you are using Babel: loader

Possible Solution
The named capturing group transform could run before the other transforms; or regexpu should get support for parsing and preserving named capturing groups

Additional context/Screenshots
While writing a reproduction to this I also found an emit bug when babel helpers are injected and the first statement is a regexp literal. Not related, just a coincidence.
