Parser handles + or %2B on the first step just fine but after it is processed by odataUri it becomes converted to a space

[tbrunner]

example $filter=ModDate ge 2006-12-30T23:59:59+00:00

the odataUri function gets called and the source string prints as shown above, but once it hits the query function it becomes

$filter=ModDate ge 2006-12-30T23:59:59 00:00

and errors because of the space instead of the + that used to exist before 00:00
