Changed gradle-plugin version in Gradle tests.

When 6.5.1 Gradle version was added, more tests have began to fail
because of legacy gradle-plugin versions (1.1., 1.2.) which are not
compatible with the new version of Gradle. This commit updates the used
version of the Gradle plugin to the latest stable (1.3.72) and makes it
configurable from tests.
