Suppress indentation when inserting newline after ''' #3780

The lint
leading_newlines_in_multiline_strings Start multiline strings with a newline.

tells us to place a new line after '''

  const sql = '''select *
from...
''';

The fix is easy. Just insert the cursor after the first set of ''' and hit return.

The problem is the resulting indentation is:

  const sql = '''
  select *
from...
''';

Note the two spaces before select.

Instead the indent should place select hard against the left hand border.

  const sql = '''
select *
from...
''';

The current method results in a changing of the format of the string (it goes from having no leading spaces to having two leading spaces).
