Class 'ProcessWire\Abbreviation' not found

[aw73]

Processwire 3.0.61 and PHP 7.1.4

I got this error when I go to the Abbreviations management and clic on "Add new" button :

Class 'ProcessWire\Abbreviation' not found in /home/public_html/tool_processwire/site/modules/Abbreviate/ProcessAbbreviate.module:155

Did you installed the module via composer?
I think not, but I will write a patch to support both installation methods (classis and composer)

I've provided a patch in commit 3752b7e

could you confirm?
