fix for ensure_first_param breaks heredocs

[felixdoerre]

Input:

  file{'/path/to/file':
    content => @(HERE),
    Contents1
    Contents2
    | HERE
    ensure => file,
  }

Command:

$ puppet-lint --fix fixed.pp 
FIXED: indentation of => is not properly aligned (expected in column 13, but found it in column 12) on line 6
FIXED: ensure found on line but it's not the first attribute on line 6

Output:

  file{'/path/to/file':
    ensure  => file,
    Contents1
    Contents2
    | HERE
    content => @(HERE),
  }

Notice, how the "fix" completely broke the HEREDOC structure. However, I am not completely sure if heredoc is considered to be supported by puppet-lint.

Expected Output:

  file{'/path/to/file':
    ensure  => file,
    content => @(HERE),
    Contents1
    Contents2
    | HERE
  }
