Fix Text Class's bugs in shaders branch (the same as #1030) (#1031)

Browse source 
* fix: remove the last M tag in svg files to make Text run in shaders branch

* fix: close the svg path manually to fix the bug of wrong stroke

* fix: remove Space mobjects in Text to fix the bug of TransformText

* feat: make Text and TextMobject equal in size

* this will lead to more bugs of setting color, so I delete it

* fix typo in text_mobject.py

* fix conflict of default size and height
