[PYD-617] Remove default for modules parameter of `install_auto_tracing`

[alexmojaki]

Currently by default:

• Modules under the root of the current module are traced if no modules are specified
• An error is raised if modules to be traced have already been imported

This means that providing no arguments will always raise an error about wanting to trace the current module which has obviously already been imported. Either modules or check_imported_modules must be specified. This is a bit weird.

This PR makes things less weird by requiring the user to specify modules. This seems like a case where explicit really is better than implicit.
