fix(compiler): Fix parsing attributes with dot in the name

Previously there was a bug when compiler was trying to parse
some complicated element attributes i.e.
element <div [attr.someProp.propSuffix]="var"></div>
turns into <div someProp="varValue"></div>

We fixed such behavior and now ensure that whole attribute
name is being parsed into html i.e.
element <div [attr.someProp.propSuffix]="var"></div>
result this html <div someProp.propSuffix="varValue"></div>
