icmr_sample route is broken

[yash-learner]

Describe the bug
Clicking the ICMR Specimen Referral Form button from a sample page takes to patient test sample page (patient/.../test_sample/.../icmr_sample) which results in internal server error

To Reproduce
Steps to reproduce the behavior:

1. Click Sample Test tab in side bar
2. Click on sample details for any one of the sample.
3. Click on ICMR Specimen Referral Form
4. See error

Expected behavior
The route should be handled if it is still in use otherwise it need to be handled accordingly. If this is not actively used and gets revamped with new upcoming Lab management module I think we can ignore this.

Hi @yash-learner,
May I take on this issue?

[yash-learner]

@JohnLu2004 Sorry for inconvenience

As we discussed on Slack this route will be going away soon and with no active users using it. I believe it's not worth fixing it, will close the issue. Please pick a new one.
