Expected behavior

1. The Datepicker label should be inactive if the underlying form control value is 'null' on initialization.
2. Clicking the label of a datepicker without a value should open the datepicker.

Actual behavior

1. The Datepicker missbehaves because the label is in active state, even though the underlying form control has the value 'null'.
2. Clicking the label does not do anything. Clicking the whitespace of the control does open the datepicker.

Resources (screenshots, code snippets etc.)

Screenshot of the first issue:

Trying to click the label of the datepicker:

html:

<mdb-date-picker [inline]="true" [locale]="'de'" [label]="'Last inspection' | translate" formControlName="lastInsepction" id="lastInsepction"></mdb-date-picker>

ts:

this.conditionDataForm = this.formBuilder.group({ lastInsepction: [null] });

It seems like that the first issue occurs only if a locale is provided. Removing the locale fixed that bug, but of course I want to keep the localization.
