matrix-dendrite-create-account parses arguments incorrectly

[madprogramer]

Describe the bug
Attempting to create an account on the dendrite server with the matrix-dendrite-create-account util fails.

To Reproduce
Enable Dendrite instead of Synapse:

# The Matrix homeserver software to install.
# See `roles/matrix-base/defaults/main.yml` for valid options.
matrix_homeserver_implementation: dendrite

ssh into your server and attempt to create a new account as follows:

/usr/local/bin/matrix-dendrite-create-account myaccount weakpassword 0 

This input is unrecognised, giving the expected usage of the command as output:

Usage: /usr/local/bin/matrix-dendrite-create-account <username> <password> <admin access: 0 or 1>

However, if admin access is not provided, an account is generated successfully with the following message:

/usr/local/bin/matrix-dendrite-create-account: line 12: [: : integer expression expected
time="2022-08-25T20:10:04Z" level=info msg="Created account: myaccount (AccessToken: SOMETOKEN)"

Expected behavior
Without any error message, we should expect to see:

time="2022-08-25T20:10:04Z" level=info msg="Created account: myaccount (AccessToken: SOMETOKEN)"

Thanks for the report! It should be fixed now!

I wonder what this is about though:

/usr/local/bin/matrix-dendrite-create-account: line 12: [: : integer expression expected
