tests/resource/aws_securityhub_member: Handle BadRequestException in …

…CheckDestroy (#16408)

Reference: https://docs.aws.amazon.com/securityhub/1.0/APIReference/API_ListMembers.html

Previously the test would pass but the CheckDestroy would fail:

```
=== RUN   TestAccAWSSecurityHub_serial/Member/invite
TestAccAWSSecurityHub_serial/Member/invite: testing_new.go:63: Error running post-test destroy, there may be dangling resources: BadRequestException:
  status code: 400, request id: 34dfc5cd-16bb-4e31-9924-6b060f6f30b7
=== RUN   TestAccAWSSecurityHub_serial/Member/basic
TestAccAWSSecurityHub_serial/Member/basic: testing_new.go:63: Error running post-test destroy, there may be dangling resources: BadRequestException:
  status code: 400, request id: 5049c5b7-be35-4fd2-93d3-4b58e13c7140
```

This error code is not listed in the API Reference, but the same exact call is used in the CheckExists function, so seems related to only when SecurityHub has been disabled after the test has been completed.

Output from acceptance testing:

```
--- PASS: TestAccAWSSecurityHub_serial (28.16s)
    --- PASS: TestAccAWSSecurityHub_serial/Member (28.16s)
        --- PASS: TestAccAWSSecurityHub_serial/Member/invite (14.81s)
        --- PASS: TestAccAWSSecurityHub_serial/Member/basic (13.35s)
```
