Describe the bug
Upgraded the gauge version to 1.5.4 from 1.0.5. I want to run a scenario with a similar command as below:

gauge run specs/dir1/spec1.spec specs/dir1/spec2.spec --scenario="Scenario 1" --scenario="Scenario 2"

Worked on previous version of gauge. Want to run spec 1 file completely with all scenarios and from spec2 file want to run 2 specific scenarios using scenario name.
With the command above it runs only spec 2 with 2 scenarios and completely skips spec 1 for some reason
Using line number for scenario execution is not possible since we get the scenario names dynamically.

To Reproduce
Steps to reproduce the behavior:

1. Initialise a gauge project
2. Run the gauge command as above

Expected behavior
Test should execute all scenarios from spec1 and specified scenarios from spec2
