Heisenbug in Metrics Test

[turtleDev]

Description Tests on Raccoon fail transiently every now and then. But resolve them self on subsequent runs.

for instance see:

1. https://github.com/raystack/raccoon/actions/runs/9524607268/job/26257713044#step:4:303 (resolved in the subsequent run here)
2. https://github.com/raystack/raccoon/actions/runs/9218661485/job/25362561868#step:4:134 (resolved on re run here)

To Reproduce The bug manifests randomly, likely due to a data race in the test code.

Expected behavior Tests should run successfully in absence of any code changes.

Additional context None
