Progress bar prints over multiple lines

[lschall]

For certain scans such as scan_minGlobalTh or tune_threshold_inj the progress bar prints over multiple lines in the terminal window (see attached screenshot). This bug does not occur on every setup. Probably a dependency version issue. The on-the-fly interpreter instantiates the normal interpreter, which relies on a second progress bar. This results in the observed error.
A proper solution to this issue is an implementation of a dedicated online_analysis class.
