~/.databrickscfg is loaded even when direct config has precedence

[nfx]

steps to reproduce:

• direct host & az resource ID
• configuration file with DEFAULT profile with token + host
• expected: azure CLI working for that host
• happens: validate: more than one authorization method configured: azure and pat error

this issue blocks databricks/terraform-provider-databricks#1848
