Fix three bugs(shaders/stroke/size) of Text Class (text_mobject.py) (#1030)

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
