Wrong Base62 module alias in 1.7.0

[ivan]

Describe the bug
After upgrading from 1.6.2 to 1.7.0 I started seeing this error when calling the EventBus.EventSource.notify/2 macro:

** (UndefinedFunctionError) function Base62.unique_id/0 is undefined (module Base62 is not available)
    Base62.unique_id()
    (sanbase 0.0.1) lib/sanbase/event_bus/event_bus.ex:84: Sanbase.EventBus.notify/1
    iex:1: (file)

This is fixed by adding the following to my config.exs file:

config :event_bus,
  id_generator: EventBus.Util.Base62

Alternatively, it should be fixed by properly referring to the module from the EventBus.EventSource.build/2 macro.

The issue seems to be introduced here:

Expected behavior
The module to be properly aliased and not reported as undefined.

Enviroment:

• OS: MacOS Monterey 12.6
• Elixir version: 1.14.0
• OTP version: 25.0
