Dropdown: Placeholder class is applied even though an option is selected

[Voltra]

Describe the bug

When the dropdown's placeholder value is the same as the select option's label, the Dropdown components adds the p-placeholder class even though it semantically makes no sense.

Currently, this is due to the fact that the placeholder class is applied when the current label is equal to the placeholder instead of when there's no value selected (e.g. !this.value).
