[Bug] autopwn2 server throws exception on html response - Part 2

[Qubasa]

Note: This is the follow-up to my previous and now closed bug in autopwn2. #7388
The error message changed a bit the problem stays the same.

Steps to reproduce

With a clean install of metasploit development and a new .msf4 folder I started the autopwn2
module and hit run:

use auxiliary/server/browser_autopwn2
run
Starting listeners...
Time spent: 12.139677811
Using URL: http://0.0.0.0:8080/02Sz7loQOQ4YJx
Local IP: http://192.168.2.243:8080/02Sz7loQOQ4YJx
The following is a list of exploits that BrowserAutoPwn will consider using.

Please use the following URL for the browser attack:
BrowserAutoPwn URL: http://192.168.2.243:8080/02Sz7loQOQ4YJx
Server started.
Starting the payload handler...
Gathering target information for 192.168.2.243
Sending HTML response to 192.168.2.243

Then I connected with my firefox browser to the given URL and this error pops up:

firefox_proto_crmfrequest - Exception handling request: uninitialized constant Rex::Exploitation::DATA_DIR

System stuff

This was on an Ubuntu machine 16.04 with a metasploit source install and the ruby version:
ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-linux]

Metasploit version

1b06e62 Land #7414, cmd_bash fix for netbsd_mail_local

Somewhat unrelated

But whats with bug number #7390 ? I had that issue too.

I should be able to get you going again, I see the broken commit (it's nothing that urgent to get in).
