Do not call functions from ExternalModules directly

[ChemiKyle]

See official documentation and issue.

Recommend something like sed s/ExternalModules::/$this->/g to correct but each line will need to be inspected.

send_rx/includes/send_rx_functions.php

Line 39 in a52189c

$q = ExternalModules::getSettings('send_rx', $project_id);

Likely replacement:
getProjectSettings()
Due to being part of a separate function file, the $this EM object is not available, $module is also not available due to being outside of a plugin page context.

The rest of the function needs a refactor as it's unrolling the (inconvenient) mysqli_result and processing on each row individually as opposed to operating on a complete result array.
