Broken report after aggregate with plugin v4.2.8

[nmilosevic]

For a long time we used older versions of Serenity (v3.7.1) and Serenity Gradle plugin (v3.6.7). Recently we've upgraded our dependencies to latest (Serenity v4.2.9 and Gradle plugin v4.2.8).

We run a relatively large suite of Cucumber tests and noticed that the report is broken after aggregate is run (see attached screenshot).

The "Functional Coverage Details" table on Summary tab is not rendered correctly (contains new column called StepsText".

The "Automated Scenarios" table in "Test Results" tab also contains one more column that shouldn't be there called "StepsText".

For now we've downgraded to Gradle plugin v4.0.46 which produces good report.
