uia_type_string should properly escape the 'backslash' character

[jmoody]

reproduced on

• briar 0.1.3b5
• briar-ios-example 1.1.5

to reproduce

requires iOS > 5
requires launching the app with instruments

#1. start a console
$ be rake sim7
#2. launch with Instruments
> start_test_server_in_background
#3. navigate to text tab
> touch_tabbar_item('Text')
#4. make the top text field the first responder
> touch("view marked:'top tf'")
#5. enter this text
> keyboard_enter_text "hello \\ world"

expected

to see "hello \ world" in the top text field

found

"hello  world"

regression

since 0.9.162 - probably since uia_type_string was introduced.

notes

only appears when running with Instruments. this is strictly a problem with escaping the '' character when passing text to uia_type_string.
