test: gstreamer: Fix failure of gstreamer_multistream_test

Multistream test failed with the following logs, to run on Raspberry Pi 4 due
to a bug introduced in one of the recent patches refactoring the code
that fails to set the camera-name property with a valid camera id
string.

WARN libcamerasrc gstlibcamerasrc.cpp:347:gst_libcamera_src_open:<libcamera> error: Could not find a camera named ''.
WARN libcamerasrc gstlibcamerasrc.cpp:347:gst_libcamera_src_open:<libcamera> error: libcamera::CameraMananger::get() returned nullptr

This patch assigns the camera->id() to the variable cameraName_ that is
later used to set element property "camera-name" needed to call the
specific camera which supports multistreams. Move the code to set
element property "camera-name" to base class GstreamerTest.
