test: [android] run tests on the first emulator in your list (#8305)

## **Description**

The objective of this pull request is to enable engineers to execute
tests on emulators that are created on their local machines, instead of
relying on a predefined emulator. This enhancement aims to decrease the
cognitive load involved in running end-to-end (e2e) tests locally.
