Do not display parameters inside the steps #116

Describe the bug
In the first version of the Allure PHP adapter, the display of steps was implemented differently. However, in the new version of the PHP adapter, there are no substeps as such. Instead, only function parameters are displayed in steps in the Allure report.

To Reproduce
Steps to reproduce the behavior:

1. Create a function with Allure::runStep() function
2. Create a sub function in the same method
3. Upload to allure and open steps

Expected behavior
There are no parameters inside the steps
