Bug: Crash when using an animation and switching to a new animated message shorter than current position

[Nemo157]

Description

If you set a message to be rendered using one of the animations, then stop it and change to a different message which is shorter than the original message but still needs animating, if the current index is longer than the new message an exception is thrown

System settings

• Operating System: Arch Linux
• Terminal in use: Alacritty
• Python version: 3.9
• Halo version: 0.0.31
• pip freeze output:

  halo==0.0.31
  log-symbols==0.0.14
  six==1.16.0
  spinners==0.0.24
  termcolor==1.1.0

Error

Exception in thread Thread-1:
Traceback (most recent call last):
  File "/usr/lib/python3.9/threading.py", line 973, in _bootstrap_inner
    self.run()
  File "/usr/lib/python3.9/threading.py", line 910, in run

    text_frame = self.text_frame()
  File ".../lib/python3.9/site-packages/halo/halo.py", line 464, in text_frame
    frame = frames[self._text_index]
IndexError: list index out of range

Expected behaviour

Reset _text_index to the start of the new message.

Steps to recreate

> python -c "import halo;halo=halo.Halo(animation='marquee',interval=1);halo.start('abc'*$COLUMNS);import time;time.sleep($COLUMNS*0.01*2);halo.start('x'*($COLUMNS+2))"

(not 100% reliable, can take a few tries to reproduce)
