Be more intelligent when parsing LaTeX

Browse source 
It seems `org-element-latex-fragment-parser` expects that a latex fragment can
really be parsed because there were false positives when it was called trying
to parse a latex environment such as `\begin{equation*}...\end{equation*}`. It
would consider `\begin{equation*}` as the fragment.
