Scott Lamb 9d6dec2565 fix incorrect Javascript private variable style
It's supposed to be a trailing underscore, not a leading underscore, as
described here:

https://google.github.io/styleguide/jsguide.html#naming-method-names
https://google.github.io/styleguide/jsguide.html#naming-non-constant-field-names

and discussed in an earlier PR:

https://github.com/scottlamb/moonfire-nvr/pull/48#discussion_r175678736

I fixed these mechanically:

rg -l0 'this[.]_' | xargs -0 perl -pi -e 's/this[.]_(\w+)/this.$1_/g'
rg -l0 '\s_\w+\(' | xargs -0 perl -pi -e 's/_(\w+)\(/$1_(/g'
