Override channel priority on installing. Add check for default channel (

#4771)

Forward fix for: #4766

Related to issue: https://github.com/conda/conda/issues/13374

1. Make sure packages are searched in particular order during install.
Use override-channel option when installing packages for smoke test:
From Conda documentation:


https://docs.conda.io/projects/conda/en/latest/user-guide/concepts/channels.html#specifying-channels-when-installing-packages
```
From the command line use --c
You may specify multiple channels by passing the argument multiple times.
Priority decreases from left to right - the first argument is higher priority than the second.
From the command line use --override-channels to only search the specified channel(s),
 rather than any channels configured in .condarc.
```

2. Add check for validating that required package is actually installed
from required channel
