[Murano] [Artifacts] "Find in selected category" js doesn't work

[Anastasia Kuznetsova]

Deploy MOS 8.0(3 controlleres, 1 hw compute, neutron vxlmn, experimental group, Murano, Artifacts)

Steps to reproduce:
1. Enable usage of glance artifacts in Glance and Murano
2. Log in Web UI
3. Upload some packages into the Murano
4. Create environment and navigate to environment components page
5. Add a couple of component to the env
6. Type the name of one of the imported packages in "Find in selected category" field and click on "Enter"

Observed result:
"Enter" triggers deletion of component from environment, not a search of desired package

This bug with "Medium" priority was marked as "Won't Fix" in 8.0, because we are almost in HCF, but we need to show that there is a problem.
