Language server resolves the same symbol to different types if pythonPath is not passed

[InSyncWithFoo]

from collections.abc import Callable  # no error

v: Callable[[int], bool]
#  ~~~~~~~~ Variable not allowed in type expression (reportInvalidTypeForm)

The reproducing steps, I hope, are:

1. pip install pyright

2. Run pyright-langserver

3. On initialization, send the following request:

   {
   	"jsonrpc": "2.0",
   	"method": "workspace/didChangeConfiguration",
   	"params": {
   		"settings": {
   			"python": {
   				"analysis": {
                       // no "pythonPath"
   					"logLevel": "Trace"
   				}
   			}
   		}
   	}
   }

Pyright should then respond with something like this:

{
	"jsonrpc": "2.0",
	"method": "textDocument/publishDiagnostics",
	"params": {
		"uri": "file:///<project-path>/.py",
		"version": 79,
		"diagnostics": [  // Only one diagnostic.
			{
				"range": {
					"start": {
						"line": 6,
						"character": 3
					},
					"end": {
						"line": 6,
						"character": 11
					}
				},
				"message": "Variable not allowed in type expression",
				"severity": 1,
				"code": "reportInvalidTypeForm",
				"source": "Pyright",
				"codeDescription": {
					"href": "https://github.com/microsoft/pyright/blob/main/docs/configuration.md#reportInvalidTypeForm"
				}
			}
		]
	}
}

A copy of the logs in my case can be found here.
