title: Django form. How hide colon from initial_text?
body: <p>I'm trying do this:</p>
  
  <pre>
  
  class NoClearableFileInput(ClearableFileInput):
      initial_text = ''
      input_text = ''
  
  class ImageUploadForm(forms.ModelForm):
      title = forms.CharField(label="TITLE",  required=False,widget=forms.TextInput(attrs={'placeholder': 'name'}),  label_suffix="")
      image = forms.ImageField(label='NEW FILE',widget=NoClearableFileInput,  label_suffix="")
  
      class Meta:
          model = Image
          fields = ('title','image')
  
  </pre>
  
  <p>There in class NoClearableFileInput cleaned value initial_text.
  In fields 'title' and 'image' use label_suffix, but from initial_text symbol ":" remained.</p>
