Lint/AmbiguousRegexpLiteral: auto-correction produces invalid code

[deepj]

It seems it fails on the regexp literal with method invocation.

Expected behavior

Auto-corrected from assert /#{device_sn_pattern}/.match('1234') to assert(/#{device_sn_pattern}/.match('1234'))

Actual behavior

assert /#{device_sn_pattern}/.match('1234'))

Left parenthesis missing after assert. It breaks Ruby syntax

Steps to reproduce the problem

Code snippet

assert /#{device_sn_pattern}/.match('1234')

Run

rubocop --only Lint/AmbiguousRegexpLiteral -a
