Invalid plist are parsed without failing, which results on invalid build()

[trufae]

Related to #86

var p = require('./');

var o = p.parse(`
<plist>
<dict>
  <key>test</key>
  <string>Testing</string>
  <key>bar</key>
  <int></int>
</dict>
</plist>
`);

console.log(p.build(o));

this code runs fine but generates an invalid plist, it should throw or fill a default value, or drop the key

current output is:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
  <dict>
    <key>test</key>
    <string>Testing</string>
    <key>bar</key>
  </dict>
</plist>

NOTE: see the missing value for the bar key
