fix: Fix the condition of the logical operators of master_user_name and master_user_password

[sshcokr]

Description

Injecting master_user_name and master_user_password will cause them to be treated as null, meaning their property values will not be applied.

An error exists in the logical operator for that property value.

• master_user_name, master_user_password are treated as null if they are not null.
• Shouldn't master_user_arn be treated as null if it is not null?
  • Changed in commit 7050620.

Motivation and Context

• Resolves fix: Wrong conditional for master_user_options #5
• Resolves fix(master_user_options): User and Pass can't be set #6
