Getting "array_shift() expects parameter 1 to be array, boolean given" error on composer require

Bug Report

Q	A
Version(s)	1.0.1

Summary

Have a project with the dependency plugin installed, and when I try to run composer require laminas/laminas-db --dev I get an ErrorException:

[ErrorException]
array_shift() expects parameter 1 to be array, boolean given

Current behavior

Current behavior is above.

How to reproduce

Described above.

Expected behavior

Composer should install the laminas/laminas-db package.

Looking at the source, there appears to be a case where an assignment operator is used where a comparison operator should be used instead: https://github.com/laminas/laminas-dependency-plugin/blob/master/src/DependencyRewriterPlugin.php#L230

If I manually edit that file and change that assignment to a == comparison operator, the composer require command is successful.
